A book written by Professor Tatsuya Kubokawa of our university, "Relearning High School Mathematics with Formulas and Examples," has been published.

Professor Tatsuya Kubogawa (*1) of the Graduate School of Graduate School of Economics of our university has published a book titled "High School Mathematics Relearning with Formulas and Examples" (November 2025, Kyoritsu Publishing).
This book is unique in that it systematically covers the content of high school mathematics with mathematics in mind, which can be used in the study of specialized fields at university. Construction starts from the basics of junior high school mathematics, such as prime factorization and greatest common divisor, and learns sequences and series, exponents and logarithms, trigonometric functions, etc. step by step. Ultimately, it develops in a flow that leads to the basic concepts of mathematics that are essential in universities, such as differentiation and integral, vectors and matrices.

Professor Kubogawa commented on the publication:
"One of the things that impressed me about my assignment at Soka University is that students are given the opportunity to relearn. Speaking of mathematics, there are lectures for students who were not good at it until high school to relearn the basics after entering university. It is possible to start learning from the basics not only in mathematics, but also in various fields such as language and data analysis.
This book is a teaching material for students who are looking to relearn mathematics. If you can overcome subjects you are not good at, such as mathematics, the academic world you will study at university will expand, and the confidence that you have challenged and overcome obstacles will be the foundation of your life. For students who want to learn about differential calculus and linear algebra at the university level after completing this book, my book, "Fundamentals of College Mathematics with Formulas and Examples" (March 2025, Kyoritsu Publishing) is available. This is written with the mathematics in mind of 'mathematics to be used' in universities and graduate schools, so I hope you will find it helpful."
